Question

我开发了一种使用MP3 SPI播放MP3文件的服务，即使它在本机上运行良好，但在服务器上发布服务后却引发异常。这是记录器捕获的异常：

No line matching interface SourceDataLine supporting format PCM_SIGNED 16000.0 
Hz, 16 bit, mono, 2 bytes/frame, little-endian, and buffers of -2 to -2 bytes 
is supported.

以下是导致错误的代码段：

String url = "http://MusicURL.mp3"
AudioInputStream stream = null;
AudioInputStream dstream = null;

try {
    URL urlFile = new URL(url);
    stream = AudioSystem.getAudioInputStream(urlFile);
} catch (UnsupportedAudioFileException e) {
    logger.error("...", e);
} catch (IOException e) {
    logger.error("...", e);
}
if (stream!=null){
    try {
        AudioFormat baseFormat = stream.getFormat();
        AudioFormat  decodedFormat = new AudioFormat(
                AudioFormat.Encoding.PCM_SIGNED,
                baseFormat.getSampleRate(),
                16,
                baseFormat.getChannels(),
                baseFormat.getChannels() * 2,
                baseFormat.getSampleRate(),
                false);
        dstream = AudioSystem.getAudioInputStream(decodedFormat, stream);
        SourceDataLine.Info info = new DataLine.Info(SourceDataLine.class, decodedFormat,
                ((int)dstream.getFrameLength()*decodedFormat.getFrameSize()));
        SourceDataLine line = (SourceDataLine)AudioSystem.getLine(info);

我非常确定将我的项目上载到服务器容器时已包含MP3 SPI JAR软件包，似乎该错误发生在最后一行。谁能告诉我为什么它不起作用...需要帮助！

无法从流信息中获取SourceDataLine
